FIGURE 3:

(a) QUESP data, or the CEST contrast as a function of RF saturation power B₁ (1 μT = 42.6 Hz), under different H₂O₂ concentrations (treated for 1 hour) were fitted to determine the proton exchange rate $(K_{ex})$. (b) $K_{ex}$ derived from QUESP data fitting increases with H₂O₂ treatment concentration. (c) Representative $K_{ex}$ maps from egg white samples untreated or treated with different H₂O₂ concentrations. *P < 0.05.
